Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsJun 09, 2022The c.1292G>T (p.G431V) alteration is located in exon 9 (coding exon 8) of the CDKL2 gene. This alteration results from a G to T substitution at nucleotide position 1292, causing the glycine (G) at amino acid position 431 to be replaced by a valine (V). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
